gross price for 1 tile

As CBN, it is used in particular for high-speed abrasive machining, e. g. for grinding and cutting hardened steels. Contrary to diamond tools, it does not decompose under the influence of temperature (the chemical affinity of carbon in any form, and also diamond - це iron in steel). CBN is actually softer than diamond (5000 HV30 - CBN, 8000-10000 HV30 - diamond), but it does not lose much of its hardness when heated (up to approx. 1500 ° C), therefore it is used for grinding carbides and diamonds at high temperatures.
